How to Build a Motion Sensor Light Circuit with an Arduino

The PIR motion sensor is a sensor which detects movement through picking up infrared radiation. Being that a person emits infrared radiation, the detector is able to detect this and react, according to the how the circuit is designed to react. The sensor can also pick up the movement of inanimate objects as well, such a rolling ball, because as ...

All About Motion Sensors - Pros, Cons and How They Work

2 days ago· For example, many dual-tech sensors combine both a PIR sensor and a microwave sensor into one unit. For a motion to be detected, both sensors must trip together. This lowers the probability of a false alarm since heat and light changes may trip the PIR but not the microwave, or moving tree branches may trigger the microwave but not the PIR.

PIR Motion Sensor - Adafruit Industries

Jan 25, 2020· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount ...

MOTION DETECTION USING PIR SENSOR

As long as PIR sensor does not detect motion in the detection area, light and fans are not function and the fan is depends on the room temperature. Once the sensor is triggered, system will have around 2 minutes to run the function. After 2 minutes and sensor does not detect any motion, light and fans will be switched OFF automatically. 2.
